Abstract

Stencil printing is the widely used method for depositing solder paste in the surface mount technology (SMT) assembly process. The aim of this study is to investigate the effect two important factors namely area ratio and aspect ratio in the stencil printing process. Taguchi’s orthogonal arrays are used to design the experiments. A total of four factors (with two levels) are considered in the experimental design. The print speed and print pressure are the two other factors considered in the study. The solder paste deposit heights were measured and recorded as response. The results were analysed by performing Analysis of Variance (ANOVA) and creating main-effects plots and response surface curves to check for any interactions and to optimize the response output. The results were also compared to work done by previous researchers and discussed critically. The ‘area ratio’ and ‘print speed’ are identified as the most important factors and there is strong interaction evidenced between ‘print speed’ and ‘aspect ratio’. The response is optimized for maximum performance and to reduce the defects from the stencil printing process.
